iMPROVEMENT INYMODE DF ADJUSTING RING S AND RlNG-RAILS lN RING ANDTRAVELER SPINNING FRAM ES Specification forming part of Iictters PatentNo. 42,829, dated May 24, 1864.

To all whom it may concern:

Be it known that I, J 01m BIRKENHEAD, of llion, in. the county ofHerkimer and State of New York, have invented a new and Improved Mode ofAdjusting Rings and Ring- Rails in Spinning-Frames; and I do herebydeclare that the following is a full and exact-'- dcscription thereof,reference being bad to the accompanying drawings and the letters ofreferencem'arktd thereon. t

To enable others skilled in the arts toniake and 'use my invention, Iwill proceed to describe its nature, construction, and operation.

The nature ,of my invention consists in placing an eccentric ring withinthe ring-rail, and gib-bushes within the holster-rail ofspinningi'rames.

In constructing ring rails for spinnin gframes great difiiculty is foundin getting the holes for thereception ot' the-ring precisely in the conter of the rail or concentric with the'spindle. When the hole is notconcentric with the spindle the-traveler is caused to bear harder uponone side of the ring, causing the ring to wear and giving the traveleravibrating .motion. The traveler is caused to revolve around the ring bythe tension of the yarn, and as its speed should be from six to seventhousand revolutions per minute it is necessary that thus giving thateven tension to the yarn which is necessary in producing good and evenyarn. -Another great evil is eausedby the wearing of the lifter pin orand shown in the drawings at 0, Figure 1. This wear generally occurs onthat ,portion of the rod or pin which is in front of the machine,andnhere my gib-bush becomes very valuable for the purpose of taking upthe motion that the lifter rod or pin may have acquired by its wear.

Fig.- 1 is a view showing a portion of a nspinning-frame with myimprovements. Fig.

2 is a view showing the eccentric-ring in an inverted'position for thepurpose of showing its eccentricity at aand b. Fig. 3 shows a portion ofbolster-rail with set-screws f and h.

Fig. 4 is a view of bush (1 with its gib j Figs.

5 and 6, front and edge view of gibs j.

' A. is the'ring-rail; B, the bolster-rail; (J, the lifter-pin; D, thespindle; g, the eccentric-ring;

a and b, the eccentric port-ions'of the ring 9 d, the bush; j, the gin;f and h, the set-screws for holding the bush and gib in position, and aset-screw for holding the ring.

I construct my improvements in the following manner: I first turnmy'ring circular as' usual on a true mandrel. 1 then give a slighteccentric form to the outside'of the lower portion of' the ring byturning it upon, a mandrel having centers one side of the true een'ters.thus giving the outer side of the lower portion of the ring the requiredeccentricity.

The eccentric-rin g isplaecd in whatever hole in the ring-rail ot' thespinning-machine is not concentric with the axis of Y the spindlepassing through the ring, and is turned. around until the spindle shalloccupy a position precisely in the center of the ring, and it is thensecured in its position by means of the set screw c, v

Fig. 1.

- The bush I construct in the ordinary manner, except making, a slot inone side for the reception of the gib, which is made as" shown in Figs.5 and 6. The bush is then placed in the hole made in the bolster-railfor its reception, and the set-screw f is screwed slightly against thegib, and the set-screw h is screwed firmly against the rear side, of thebush in?" for the purpose of holding it in its proper position. Now,when the lifter pin or rod U becomes worn, the rin g-rail A is throwntoward the front side of the machine, which causes the traveler to havean irregular bearing upon. the ring, thus causing a greatwear of thering,

increased tension ofthe yarn, and, consequent- 1y, uneven and worthlessyarn. With my gib Within the bush d, and the set-screw f to screwagainst it, the. ring-rail can be brought back to its original position.Whatever spindle may not then be concentric wit-h its respective ringmaybe brought precisely concentric by the use of my eccentric-ring. Thuswith the combined use of my eccentric-ring and gibbash a spinningmachine may hemacle to work very perfectly.

I do not claim as my invention the use of the firing placed within therail A, neither do 1lgelgtim the bush d independent of the gihj LettersPatent of the United States, is-- l. The employment of theeccentric-ring 9,

What I doelim, and wish to secure by as and for the purpose hereindescribed and set forth. I
